I don't need a referral as long as they are listed on my insurance companies website. There are plenty of endos I can see. Why exactly would a person with CFS benefit from seeing an endocrinologist?? I did see one a few years ago before I got mono and then CFS and my labs were normal. However, is it true that CFS can destroy the thyroid? What would I say to the endo when he/she asks why I came to see them? Also, what exactly is an osteopath and why would a person with CFS benefit seeing one?
